Subject: [kea-dev] Binding problem 2: Kea does not connect to site
local IP and "All_DHCP_Servers address"
Message-ID: <[email protected]>
Content-Type: text/plain; charset=UTF-8; format=flowed
Kea binds to link local IP and "All_DHCP_Relay_Agents_and_Servers
address" (FF02::1:2) but not to site local IP and "All_DHCP_Servers
address" (FF05::1:3).
What to tell the relay where the packets should go to?
